To all ywhom t may tonne/11:

lle it known that l, (lithium-1s J. NAsn. a citizen of the United States, and resident of (hirugo. rounty of (look. and State of Illinois. have invent-sii errtain new andy usei'nl improreinents in Draft l'-igging for (lars, of whieh the following is a speritiea* tion, and which are illustrated in the acronipanying drawings. forming a part thereof.

The invention relates to nieehanisins for transmitting pulling a nd hutling stresses to the undcrframing of ay ear; its object being to secure great strength while avoiding eX- eessive weight or mniplirated constructions and operations. i

An embodiment of the invention is illnstrated in the accompanying drawings, in which-- Figure l. a detail longitudinal forth ral aeciion ol' 'the underfraining of :i car and of the draft rigging on the renier line of draft; Fig. 2 is a il .ail plan View of the saine, partly in section; and Figs. 3 and l are transverse sectional views on the lines Il -l and 4M# respeetiiely. of Fig. 2.

pair of renter sills is shown :it 10,y `10; an end sill :it 1-"1, and a butler plate at .The eoupler is represented at 13. The roupier extension takes theI forni of a yoke eoniprising longitudinal side members 14, 15. a shell or easing 15 for innlosing the enshioning elements, and a rear end 17 rein formed hv a transverse hailing hos-s 1S4 T he side members 1l, 15, of the coupler extension are slotted as shown at 19, to receive a key Qi). which also pgssei t'h'iongh a suitable transverse slot in the Stank of the Coupler 13 and through elongated slots, as 21, in the sills 10 and in the draft platos allixed thereto. The draft plates 22 are provided with helling lugs 23, *24, against which the hailing boss 13 of the coupler extension nox xnally bia The easing 16 of the Coupler extension rides upon a earrier plate "Z5 which is bolted to the sills 10.

The devine shown as applied to the so (called twin spring type of gear, wherein a pair of springs4 loeated side by side and ant-- ing in multiple is employed. The easing 16 is arr-,ordingly designed to properly house and hold in piave sue-h pair of springs, and niajy', of course, be differently shaped when the cushioning or shocknbsorbing elements l are of different form.

The springs are shown at 26, 27, and are housed within the casing 16 and react between its rearward wall 17 and a bearing v block against the forward face of which the inner end of the shank of the coupler 13 bears. The block 28 is cored out to reduce 60 .its weight. without detraeting materially from its strength, and comprises frontl and rear plates 29, 30, and connecting webs 31, 32. 33, the last-named being located on its, median horizontal plane and being slotted to* receive a key 34, which extends through elongated slots 35 in the side members of the coupler extension, and similar slots 36 in the draft plates When the parts are assembled the springs 2G. 27. hold the key 34 at the forward ends of the slots 3?). 3G, the key 20 at, the forward ends of. the slots 19, and the bufling boss 18 in engagement with the bufling shoulders 23, :24. Under draft stresses the coupler extension is drawn forward, the key 20 sliding in the slots 21, the rear end of the extension romplessing the springs against the block 28. which transmits the stresses through the key 2H to the draft plates. In bufiing' the 80 coupler 13 moves inward, the key 20 traveling in the slots 19 andll, the block 28 and Y key' 34 being forced barikwardly, the springs being compressed against the rearward end of the coupler extension and the stresses being transmitted through the bearing boSS 1S to the bniling shoulders 23, Q4.

I claim as my invention- In a draft rigging, in combination, a air of slotted draft plates having bufling a utv ments, a coupler extension comprising Va. spring-inelosing easing engageable with the buitng shoulders and open at its forward end, a nearing block normally forward .of and slidable within the open end of the casing, a spring housed within the casing and reacting between the inner end thereof and the bearing block, and a key 'set through th block and slots in the draft plates.
